Modules

prelude

Convenience re-export of common members

Random number generators and adapters

Traits

CryptoRng

A marker trait used to indicate that an RngCore or BlockRngCore implementation is supposed to be cryptographically secure.

Fill

Types which may be filled with random data

Rng

An automatically-implemented extension trait on RngCore providing high-level generic methods for sampling values and other convenience methods.

RngCore

The core of a random number generator.

SeedableRng

A random number generator that can be explicitly seeded.

Functions

random

Generates a random value using the thread-local random number generator.

thread_rng

Retrieve the lazily-initialized thread-local random number generator, seeded by the system. Intended to be used in method chaining style, e.g. thread_rng().gen::<i32>(), or cached locally, e.g. let mut rng = thread_rng();. Invoked by the Default trait, making ThreadRng::default() equivalent.
